Subject: [PATCH 00/14] drm/panel: Transition away from using
 mipi_dsi_*_write_seq()

Transition away from mipi_dsi_generic_write_seq() and
mipi_dsi_dcs_write_seq() to mipi_dsi_generic_write_seq_multi()
and mipi_dsi_dcs_write_seq_multi() respectively.

This is addressing one of the gpu todo items [1]

Used Coccinelle to make the code changes.Semantic patch:
